 This is a way to print all the elements of an array contained in a
 GET OR POST method. It translates all the html special characters,
 and presents them as a key : value series:
 -------------------------------------------------------------------
 if ($_GET) {
    echo "<pre>";
    echo htmlspecialchars(print_r($_GET, true));
    echo "</pre>";
 }
